Abstract: A liquid crystal display (LCD) device has a housing acting as a conductor, a plurality of circuits, and at least a filter unit. Each circuit has a reference voltage terminal electrically connected to a reference voltage level. When the reference voltage terminal of each circuit is electrically connected to the housing, one filter unit is electrically connected between the housing and a ground terminal. When the housing is electrically connected to the ground terminal, a plurality of filter units are respectively connected between the housing and the reference voltage terminal of each circuit.

Abstract: A multi-lamp system for driving a lamp set having a first lamp and a second lamp comprises a driving circuit for converting a DC signal to an AC signal, a transformer having a primary side coupled to the driving circuit and a secondary side for outputting the AC power, and a current balance circuit coupled to the low voltage terminal of the lamp set for balancing the current values flowing through the first lamp and the second lamp. The current balance circuit comprises a magnetic core, a first winding coupled to the first lamp and a second winding coupled to the second lamp. The first winding and the second winding are wound on the magnetic core and have the same coil number.

Abstract: A system for driving a plurality of lamps is disclosed to balance currents flowing through the lamps by means of impedance matching. According to the multi-lamp driving system of the present invention, a balancing controller is employed to match the impedance of each lamp path so as to regulate currents flowing through the lamps to be substantially the same.
